RAILWAY ROAD-BED.

Specification of Letters Patent.

Patented Jan. 15, 1907.

Application filed Marci. 28, 1906. Serial No. 308.400.

To all whom it may concern.-

Be it known that I, LUTHER R. ZOLLINGER, a citizen of the United States,residing at Philadelphia, in the county of Philadelphia and State ofPennsylvania, have invented certain Improvements in Railway Road- Beds,of which the following is a specification.

This invention contemplates the production of a permanent road-bed forrailways subject to heavy traffic, which gradually destroys theconstructions now employed and necessitates constant repairs at greatexpense, accompanied by frequent interference with the handling oftrains.

My improved construction consists, essentially, of a solid concrete orother artificialstone bed preferably forming a complete floor under therails and extending below the frost-line, having iron stringers embeddedtherein beneath the rails, means for securing and detaching the railswithout disturbing the bed, and provisions for taking care of thedrainage and carrying signaling apparatus.

In the accompanying drawings, Figure 1 represents a plan view of asection of roadbed made in accordance with my invention. Fig. 2 is asectional view taken on the line 2 2 of Fig. 1. the line 3 3 of Fig. 1.Fig. 4 is a plan view of a section of a rail with its connections. Fig.5 is a sectional view taken on the line 5 5 of Fig. 4, and Fig. 6 is asectional view representing the edge of the bed with the drainstherefor.

As shown in the drawings, the bed 1, preferably stiffened bystrengthening members 1, rests on the foundation 2 below the frostlineand extends as a complete floor beneath the system of tracks formed bythe rails 3. Embedded in the concrete beneath the rails are the I-beams4, which extend parallel to and act as stringers for supporting them, acushion formed by a layer 5 of any suitable material being placedbetween the rails and the stringers. To secure the rails in place, sothat they can be adjusted and removed without disturbing the bed,sockets 6 are formed in the concrete, with metal coils 7 embeddedtherein to form threads for engaging the bolts or screws 8, which passthrough the clips 9 for securing the rails by engaging the flanges 3,the washers 10 for alining the rails by engaging the flanges, and

Fig. 3 is a sectional view taken on' the flanges 4 of the I-beam forstrengthening the structure, the washers preferably being of rectangularform, with the boltholes placed eccentrically therein, so that thepositions of the rails can be adjusted in alining by turning suchWashers.

The bed is provided with a surface configuration and drains, whichpermit the water to flow therefrom, longitudinal slopes 11 andtransverse slopes 12, leading to drains 13, which discharge into thegutters 14 and thence into the conduits 15, openings 16 being providedin the intermediate stringers to permit the water to pass. Longitudinalconduits 17 are formed in the bed for the passage of wires, rods, or thelike necessary for signaling, shifting switches, or such purposes.

As shown in Fig. 5, the I-beam 4 is tilted from the vertical line 18, sothat its axis lies in the line 19, making an angle a: therewith, wherebythe top of the rail is tilted at a like angle to the horizontal. Thisangle corresponds to the coning of the car-wheels, and the tilt of therails provides a broad bearing for the wheels and reduces wear thatobtains in the usual constructions.

Having described my invention, I claim 1. A railway road-bed comprising,in combination with a rail, an artificial-stone support extendingsubstantially continuously between and along beneath said rail, and ametal stringer embedded in said stone and extending along the length ofthe rail, said stringer supporting said rail without the intervention ofa cross-tie.

2. A railway road-bed comprising an artificial-stone floor, metal beamsembedded in said floor, each beam being provided with a web and afianged top, and rails extending along and supported by the respectivebeams, said rails being fixed directly to the flanged tops of therespective beams without the intervention of a cross-tie.

3. A railway road-bed comprising an artificial-stone support, I-beamsembedded in said support, rails extending along and supported by saidI-beams without the intervention of a cross-tie, and means for securingsaid rails in said positions said support extending continuously betweenthe rails and along the whole or the greater part of the length thereof.

4. A railway road-bed comprising a continuous artificial-stone supportwith means therein for engaging a bolt, in combination with a rail, aclip for engaging said rail, a washer having an eccentric hole thereinfor engaging and adjusting said rail, and a bolt engaging said clip andwasher to said bed.

5. A railway road-bed comprising an artificial-stone support providedwith a socket having a metal thread set therein, in combination with arail, a clip for holding said rail, a washer having an eccentric holetherein for engaging and adjusting said rail, and a bolt passing throughsaid clip and washer into en, gagement with the thread in said socket.

6. A railway road-bed comprising a solid artificial-stone base extendingalong and between the rails, I-beams embedded in said base, railsextending along and supported by said I-beams, and reinforcing membersem- LUTHER R; ZOLLINGER.
